title: Preoperative embolization of hypervascular head and neck neoplasms using microfibrillar collagen.
abstract: Microfibrillar collagen is a bovine collagen material that promotes hemostasis. When mixed with contrast material it makes a fine slurry that is easily injected through small catheters. Experience with preoperative embolization of head and neck neoplasms in six patients indicates that microfibrillar collagen slurry is a highly effective, easy to use embolic material for occlusion of highly vascular neoplasms.
